from a quick look, it looks ok..you're getting the hip extension part that everyone seems to struggle with at first.
-your front rack position looks like it could do with a bit of flexibility work?
- how wide are you gripping the bar? if you're long armed/short torso like me, a wider grip may help. I find a narrow grip, even one like id use for a deadlift leads to my 'jumping point' being far too low, really zapping my power. so widening the grip lets me bring the weight closer to my hips before 'exploding'. i can't exactly tell from the shots but you do like kinda narrow

https://spencergarnold.wordpress.com/2013/04/02/grip-width-in-the-clean/'If your grip is too narrow, and especially if you have long arms, the bar is likely to hit too low on your quads when you transition into the second pull. This horizontal application of force into the barbell will push the bar out away from your body thus making the clean harder and more inefficient. The grip must allow the bar to make contact with your upper thigh in the standing position.'
hope this helps!
